I think people are addicted to social media. I think people feel entitled to be able to use other people's technology to spew whatever rhetoric they want. Of course I'm morally against censorship, but I am for private entities regulating their products/technology how they see fit.
I never understand why so many people who hate Facebook not only use Facebook but are addicted to it as well. I guess it's not much different than drug addicts who hate their drugs but are nevertheless addicted to it.
One final thought: Imagine a bunch of devil worshippers coming to CC and posting pro-Satan garbage along with videos of them doing satanic rituals... Should they be censored? Sure, if the owner of CC decides it ought to be. The owner can make an explicit list of rules we must follow, but he/she isn't held and bound by it... He/She is free to ban anyone for any reason as this is his/her site. No one forces us to be here... no one forces anyone else to have Facebook, Twitter, Instagram, etc... In this, I applaud the OP for deleting everything he is against.
